3 Claims. (Cl. 155-79) The present invention relates to a demountable high chair.

The primary object of the invention is to provide a high chair whose seat can be removed from the supporting legs for cleansing in wash trays and the like.

Another object of the invention is to provide a high chair having a seat which can be transferred to a motor vehicle for holding an infant riding therein. In order to carry out these objects, the supporting legs are foldable and easily stored in a small space while not in use.

Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings, in which:

Figure l is a side view of the invention;

Figure 2 is a front view of the structure shown in Figure I;

Figure 3 is a top plan view with parts broken away for convenience of illustration;

Figure 4 is an enlarged fragmentary sectional view taken on line 4-4 of Figure 1 looking in the direction of the arrows;

Figure 5 is a plan detail of the structure of Figure 4, partially broken away for convenience of illustration;

Figure 6 is an enlarged fragmentary detail view partially broken away and in section illustrating the tray of the chair secured to the upper rail of the legs of the chair;

Figure 7 is a side elevation of a modified form of the invention;

Figure 8 is a front view of the structure shown in Figure 7;

Figure 9 is an exploded side elevation of the structure of Figure 7 which illustrates how the seat and tray are removable from the supporting legs; and

Figure 10 is an enlarged fragmentary sectional view taken on line 10-10 of Figure 7 looking in the direction of the arrows.

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference character C indicates generally a demountable high chair having a leg structure 10 and a seat structure 11. The leg structure 10 includes a pair of spaced apart inverted U-shaped tubular legs 12, 13, connected together by a pair of folding brace assemblies 14, 15. The brace assemblies 14, have a pair of bracing arms 16 and 17, pivotally connected together at 18 with their ends pivotally connected to the legs 12 and 13 at 19.

A seat structure 11 is preferably molded from one piece of material, having a generally horizontal seat portion 20 with upwardly extending side arms or walls 21, coming together at 22 in a gradual rounded corner. Extending from the seat and upwardly and forming part of the side walls or arms 21 is the back 23. The back 23 joins the seat portion 20 and the side arms 21 with a rounded corner, as best illustrated at 24. The object of having corners rounded is to make it easy to cleanse when washing the seat 11.

are formed on one end of resilient spring membersZSI and pass through holes 30 formed in the reverse bend 25 of the arms 21 and into the holes 31 formed along the side of the upper rail 27 of the supporting legs 12, 13 to lock the arms of the chair to the rails 27 until the operator grasps the button 32, pulling the pins 28 out of the holes 30 and releasing the arms 25 from the rails 27.

A removable tray 33, referring particularly to Figure 6, is secured to the upper rail 27 by inverted goose-neck brackets 34. The end 35 of the brackets 34! enter through an opening 36 into the rail 27 to support the tray 33 in operating position.

Referring to Figures 7 through 10, a modified form of the invention is illustrated. In this form of the invention reverse bends 25A of the arms 21A partially encircle the rail 27A, as illustrated at 25B. In order to apply the seat to the upper rails 27A of the legs, referring particularly to Figures 9 and 10, the upper ends 37 of the legs are reduced in diameter so that the reverse bend 25A can slip over the same from the position shown in Figure 9.

After the arms 21A of the seat are brought to the position shown in Figure 7, the tray 33A is brought into position as illustrated, the reverse bend 34A entering the upper rail 27A as indicated at 38. This will hold the tray 33A and at the same time will more or less interlock the arms 21A of the seat, preventing them from coming forward off the rails 27A.

A pair of hooks 39, illustrated by broken lines in the drawings of both modifications, are adapted to enter loops 40 forming part of the back of the chair, as best illustrated in Figures 1, 2, 3, 7 and 9. The hooks 39 are adapted to slip over the top of the back of a motor vehicle seat when the device is being used for transportation of an infant within a motor vehicle. The hooks 39 prevent the seat from moving forward when the vehicle is brought to a stop. The hooks 39 would only be used when the seat was used in connection with motor vehicles.

In carrying out the primary object of this invention, the seat structure 11 is removed from the upper rails of the legs as above described, and brought to a wash tray or the like for cleansing. The leg structure 10 can be easily folded into a small space while not in use.

Having thus described the preferred embodiments of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claims.

What we claimed is:

l. A demountable high chair comprising a pair of inverted U-shaped leg structures, each of said leg structures having a pair of vertically spaced apertured ears thereon, the confronting ears on said leg structures being in alinement with each other, a pair of brace members pivotally secured together intermediate their opposite ends, each of said brace members having hooked ends thereon that are pivotally mounted in said ears so that the brace members are in crossed relation to each other for releasably securing said leg structures in spaced parallel relation, said leg structures each having a generally horizontal bight portion connecting the front and rear portions thereof, a molded seat structure, means on said molded seat structure encompassing said bight structures supporting said seat structure on said leg structures, and a tray removably supported on said bight structures.

2. A device as claimed in claim 1 wherein means are Patented May 16, 1961- provided-for releasably locking said seat structure to said I leg structure.

said seat structure from the back' of a motor "vehicle 5 seat.
